Thus, in 3 d display device 1, can be the input operation that unit detects the user with each alternative effectively, thereby can prevent misoperation.
< selection judging part >
Select judging part 72 whether to select alternative in order to judges.Be specially, select judging part 72 and judge in the surveyed area of region setting part 71 outputs whether contain the corresponding coordinate figure of user's contact position with 6 outputs of coordinate Calculation portion.If the coordinate figure of contact position is included in the surveyed area, then selects judging part 72 to be judged as the user and selected the alternative corresponding, and this judged result is exported to contents processing portion 2 with this surveyed area.
< grand output adjustment part >
The grand output that is visually swelled from display screen 51 in order to the adjustment alternative in grand output adjustment part 73.Be specially, grand output adjustment part 73 generates the control signal that reduces in order to the grand output d that makes the alternative that the user selects, and this control signal is exported to contents processing portion 2.Like this, in the middle of the alternative that display screen 51 is shown, the grand output of sense of vision of the alternative that the user selected is lacked than the grand output of the sense of vision of non-selected alternative.Thus, therefore the user can improve user's visibility and operability from visually telling selecteed alternative and non-selected alternative.
< layout changing portion >
Be specially; When region setting part 71 has reset surveyed area; Layout changing portion 74 generates the control signal that the demonstration of the alternative of demonstration in the display screen 51 is widened at interval according to the coordinate information of the surveyed area that resets, and this control signal is exported to contents processing portion 2.
Thus, can widen the demonstration interval that is presented at the alternative in the display screen 51, thereby can improve user's visibility and operability with the surveyed area that resets.
< region setting part is to the setting of surveyed area >
Below, according to Fig. 2 and Fig. 3, the setting that 71 pairs of surveyed areas of region setting part once carry out is described.Region setting part 71 is calculated as the extensive magnitude and the direction of expansion that enlarge surveyed area and will add when setting surveyed area.
< computing method of extensive magnitude >
At first, come the computing method of the extensive magnitude of the surveyed area that declare area configuration part 71 sets with reference to Fig. 2 and Fig. 3.
Fig. 2 is used for the mode chart of the computing method that the extensive magnitude of the 71 pairs of surveyed areas in declare area configuration part calculates.In Fig. 2, P1 is the viewing area of alternative OB on display screen 51; P2 is that the looking of alternative OB that the user sees recognized the position; A is the surveyed area on the touch screen 52, and it is used for detecting the input operation that the user makes to alternative OB; P3 is, seems to be in to look the alternative OB that recognizes position P2 along perpendicular to the direction projection of display screen 51 view field to the touch screen 52; I is the zone that can contact according to the user that experimental result is known.
As shown in Figure 2, surveyed area A is made up of fundamental region A1 and enlarged area A2.Fundamental region A1 is located on the viewing area P1 of the alternative OB that display screen 51 shown, and the size of fundamental region A1 is identical with viewing area P1.That is, fundamental region A1 is the equal of the surveyed area a1 on the existing touch screen type three-dimensional display screen 151 shown in Figure 9.
Through 3 d display device 1, see that from user's angle the alternative OB that is shown on the viewing area P1 of display screen 51 can seem to be in to look and recognize position P2.Learn according to experimental result: under above-mentioned situation, when the user is in when looking the alternative OB that recognizes position P2 and carrying out input operation seeming, the user can touch certain position among the contact area I that comprises fundamental region A1 and the P3 of view field pell-mell.Why this phenomenon can take place, be because user's visual sense and the cause that the body sense varies with each individual.
Therefore in the past the technology, when between user's contact position and viewing area P1 (fundamental region A1), position deviation having occurred, touch screen 52 just can't detect the input operation that the user makes alternative OB.
To this, region setting part 71 enlarges sets out the big surveyed area A than the viewing area P1 of alternative OB on display screen 51.Be specially, region setting part 71 is set out the surveyed area A that is formed by fundamental region A1 and enlarged area A2 addition.
Below, the computing method example that the extensive magnitude of 71 couples of surveyed area A of region setting part is once calculated is described.
< computing method 1 >
The computing method 1 of the extensive magnitude of surveyed area A at first, are described with reference to Fig. 2.
Longitudinal direction (y axle) extensive magnitude of surveyed area A is made as AH (unit is mm) (with reference to Fig. 4), and region setting part 71 calculates longitudinal direction extensive magnitude AH according to following calculating formula 1.
AH [mm]=SH * (h-d)/(L-d) [mm] ... (calculating formula 1)
Equally, transverse direction (x axle) extensive magnitude of surveyed area A is made as AW (unit is mm) (with reference to Fig. 4), region setting part 71 calculates transverse direction extensive magnitude AW according to following calculating formula 2.
AW [mm]=SW * (h-d)/(L-d) [mm] ... (calculating formula 2)
In aforementioned calculation formula 1 and calculating formula 2; L is the distance (unit is mm) between display screen 51 and eyes of user; H is that alternative OB visually swells the grand output (unit is mm) that from display screen 51; D is the distance (unit is mm) till display screen 51 to the position that supplies to detect user's input operation; SH is the longitudinal direction length (unit is mm) of the display screen 51 when delimiting the short transverse of input display 5 for longitudinal direction, and SW (not having diagram) is the transverse direction length (unit is mm) of the display screen 51 when delimiting the Width of input display 5 for transverse direction.
In this embodiment, if adopt touch screen 52 to be used as entering apparatus, till then from display screen 51 to the position that supplies to detect user's input operation is the thickness of touch screen 52 apart from d.In addition,, till then from display screen 51 to the position that supplies to detect user's input operation be:, detect the detection distance till the active position of user's input operation to range sensor from display screen 51 apart from d if adopt range sensor to be used as entering apparatus.
Distance L between display screen 51 and eyes of user for example can be: the mean value of the spacing of the spacing of display screen 51 and user's right eye and display screen 51 and user's left eye.It maybe can be a certain side's in display screen 51 and the right and left eyes spacing.
Like this, region setting part 71 is the longitudinal direction extensive magnitude AH that calculate according to aforementioned calculation formula 1, appends on the direction of wherein at least one end at y axle two ends of fundamental region A1.In addition, region setting part 71 is the transverse direction extensive magnitude AW that calculate according to aforementioned calculation formula 2, appends on the direction of wherein at least one end at x axle two ends of fundamental region A1.Thus, region setting part 71 is set out the surveyed area A that is formed by fundamental region A1 and enlarged area A2 addition.
As stated, the above-mentioned calculating formula 1 of region setting part 71 utilizations is calculated extensive magnitude AH, AW with calculating formula 2, and sets surveyed area A.Surveyed area A is expanded to the P3 of view field is included in interior degree.Like this, surveyed area A and contact area I are integrated,, also can detect the input operation that the user is done alternative OB effectively even therefore between viewing area P1 (fundamental region A1) and user's contact position, position deviation occurs.
In addition, if utilization computing method 1 are calculated the extensive magnitude of surveyed area A, then favored area configuration part 71 is set in [mm] above SH of SH * (h-d)/600 * (h-d)/(100-d) below [mm] with the longitudinal direction extensive magnitude AH of surveyed area A.Equally, favored area configuration part 71 is set at [mm] above SW of SW * (h-d)/600 * (h-d)/(100-d) below [mm] with the transverse direction extensive magnitude AW of surveyed area A.
Generally speaking, the average length of people's arm is about 600mm.Therefore, (L-d) is decided to be 600mm, and the expansion lower limit of enlarged area A2 is decided to be [mm] or SW * (h-d)/600 [mm] of SH * (h-d)/600.Through like this, under the situation that the user elects to alternative OB with finger, when the user from from input operation is carried out in display screen 51 position farthest the time, can prevent the maloperation that position deviation caused at this moment.
In addition, correctly be familiar with the alternative OB that shows on the display screen 51 in order to make the user, the distance between display screen 51 and the eyes of user generally need keep more than about 100mm.Therefore L is decided to be 100mm, and the expansion higher limit of enlarged area A2 is decided to be [mm] or SW * (h-d)/(100-d) [mm] of SH * (h-d)/(100-d).Through like this, when the user from when input operation is carried out in display screen 51 nearest positions, can prevent the maloperation that position deviation caused of this moment.
< computing method 2 >
Next, the computing method 2 of the extensive magnitude of surveyed area A are described with reference to Fig. 3.
Fig. 3 is used for the mode chart of other computing method that the extensive magnitude of the 71 couples of surveyed area A in declare area configuration part calculates.As shown in Figure 3; The right eye that can realize stereo visual effect of the alternative OB that display screen 51 is shown is made as p (unit is mm) with image and left eye with the position deviation amount between image; This moment, favored area configuration part 71 was decided to be vertical (y axle) direction extensive magnitude AH of surveyed area A below the above SH * p/ of 20 * p/ (75+p) [mm] (75+p) [mm], and horizontal stroke (x axle) the direction extensive magnitude AW of surveyed area A is decided to be below the above SW * p/ of 20 * p/ (75+p) [mm] (75+p) [mm].
At this, learn the user on audiovisual display screen 51 during images displayed through experiment, regular meeting produces the sight line change in location about 20mm at least during because of the action of health.Therefore the expansion lower limit with enlarged area A2 is decided to be 20 * p/ (75+p) at least, so just can prevent the maloperation that causes because of the sight line change in location of following the user's body action.
In addition; In the axial space of z; Promptly in the space of delimiting perpendicular to the direction of display screen 51; If there are user's eyes, then the maximum fore-and-aft distance of eyes of user between the viewing area P1 of vertical projection position on the display screen 51 and alternative OB just is SH, and the maximum transversal distance is SW just.Therefore; With enlarged area A2 transversely with vertically on the expansion higher limit respectively be decided to be SH * p/ (75+p) [mm], SW * p/ (75+p) [mm], the below of recognizing position P2 of looking of so just can be effectively expanding surveyed area A to alternative OB that the user sees.
In addition; Computing method 2 need not use the grand output h of distance L between display screen 51 and user, alternative OB and till effective detection position of display screen 51 to input operation apart from d, so region setting part 71 can easily be set surveyed area A.
< calculating of direction of expansion >
Then, with reference to Fig. 2 and Fig. 4, the computing method that region setting part 71 is calculated the direction of expansion of surveyed area A describe.
Generally speaking, user's contact position has the tendency at center of the viewing area P1 deflection display screen 51 of the alternative OB that shows from display screen 51.For example shown in Figure 2, when selecting object OB to be presented at the top of user's eye-level display, the user has the tendency that touches fundamental region A1 below.
Therefore, through with the middle auxocardia of surveyed area A, just can make the offset direction of direction of expansion and user's contact position of surveyed area A consistent to display screen 51.Be specially, the centre coordinate of the centre coordinate of 71 pairs of display screens 51 of region setting part and the viewing area P1 of alternative OB compares, and calculates the direction of expansion of surveyed area A thus.
(a)～(d) of Fig. 4 is a routine vertical view of the direction of expansion of surveyed area A.Shown in Fig. 4 (a), region setting part 71 can add enlarged area A2 with the mode of surrounding fundamental region A1 periphery, sets surveyed area A thus.Therefore no matter where user's eyes are in respect to alternative OB, even above-mentioned position deviation has taken place, also can detect the input operation that the user does alternative OB effectively.
In addition, if region setting part 71 is with the middle auxocardia of surveyed area A to display screen 51, then such surveyed area A that sets gets final product shown in Fig. 4 (b)～(d).For example; When the centre coordinate of display screen 51 is positioned at the lower right of centre coordinate of viewing area P1 of alternative OB; Then region setting part 71 is as Fig. 4 (b), and the right and the additional enlarged area A2 in base to fundamental region A1 set surveyed area A thus.
In addition, when the centre coordinate of display screen 51 was positioned at the top of centre coordinate of viewing area P1 of alternative OB, then region setting part 71 to the additional enlarged area A2 of the top margin of fundamental region A1, was set surveyed area A thus as Fig. 4 (c).
Again it, when the centre coordinate of display screen 51 was positioned at the left of centre coordinate of viewing area P1 of alternative OB, then region setting part 71 to the additional enlarged area A2 in the left side of fundamental region A1, was set surveyed area A thus as Fig. 4 (d).
Such shown in Fig. 4 (b)～(c), set surveyed area A through middle auxocardia to display screen 51, can prevent unnecessarily to set surveyed area A, and prevent that the surveyed area A that sets from overlapping.
< processing in the 3 d display device >
Below, the processing in the 3 d display device 1 of this embodiment is described with reference to Fig. 5 and Fig. 6.
< handling example 1 >
The base conditioning of the 3 d display device 1 of this embodiment at first is described with reference to Fig. 5, is promptly handled example 1.
Fig. 5 is the process flow diagram of the processing example 1 of the 3 d display device 1 in the embodiment of the present invention.As shown in Figure 5, handle example 1 and have step S1～S11.
At first, the picture material (S1) of contents processing portion 2 playback records in medium M etc., and generate the view data of each unit image.
Whether next contains alternative OB (S2) such as button in the view data of the per unit image that 2 judgements of contents processing portion generate.
If do not contain alternative OB (being " denying ") in the view data at S2; Then contents processing portion 2 makes the coordinate information of view data and each object set up corresponding relation; Then they are exported to three-dimensional depiction engine 3 (S3), thereby make display screen 51 demonstrate the image shown in the view data.
On the other hand; If contain alternative OB (being " being ") in the view data at S2; Then contents processing portion 2 makes the coordinate information of view data and each object set up corresponding relation; Then they are exported to the three-dimensional depiction engine 3,, and the coordinate information of alternative OB exported to control part 7 (S4) so that display screen 51 demonstrates the image shown in the view data.
The region setting part 71 of control part 7 has been obtained behind the coordinate information of the alternative OB of contents processing portion 2 outputs; According to this coordinate information; Calculating is used to enlarge direction of expansion and the additional length that surveyed area A, wherein this additional length that is extensive magnitude AH, AW (S5).
Then, region setting part 71 is set each alternative OB surveyed area A (S6) separately according to the extensive magnitude AH, AW and the direction of expansion that in S5, calculate.Be specially, region setting part 71 is directed against the corresponding fundamental region A1 of viewing area P1 of the alternative OB that shows with display screen 51, and extensive magnitude AH, AW to the prescribed direction additional calculations goes out set surveyed area A thus.
Then, layout changing portion 74 changes the layout (S9) of the alternative OB of display screen 51 demonstrations.Be specially; The coordinate information of the surveyed area A that layout changing portion 74 resets according to region setting part 71; The control signal of generation in order to the display position of corresponding alternative OB in display screen 51 changed, and this control signal exported to contents processing portion 2.Contents processing portion 2 has obtained after the control signal of layout changing portion 74 output, changes the former coordinate information of alternative OB into shown in this control signal coordinate information, then this coordinate information is exported to the three-dimensional depiction engine 3.Thus, new settings that can corresponding surveyed area A, the image after the layout that makes display screen 51 demonstrate alternative OB is changed.
On the other hand, if there is not overlapping part (being " denying " at S7) among the surveyed area A, then region setting part 71 does not carry out the processing of step S8 and S9.
Then, select judging part 72, judge whether alternative OB is selected (S10) with reference to from the coordinate information of the surveyed area A of region setting part 71 outputs and from the coordinate figure of the expression user contact position of coordinate Calculation portion 6 outputs.Be specially, select judging part 72 to obtain the coordinate figure of expression user contact position from coordinate Calculation portion 6 after, whether the coordinate figure of judging this user's contact position is included in the coordinate domain of the surveyed area A that region setting part 71 sets.
If the coordinate figure of contact position is not included in the coordinate domain of surveyed area A interior (being " denying " at S10), then selects judging part 72 to be judged as no any alternative OB and be selected, and repeat the processing of S10, till having alternative OB to be selected.On the other hand, if the coordinate figure of contact position is included in the coordinate domain of surveyed area A interior (being " being " at S10), then selects judging part 72 to be judged as and be selected with the corresponding alternative OB of this surveyed area A.Then, select judging part 72 to generate in order to expressing the selecteed control signal of this alternative OB, and this control signal is exported to contents processing portion 2.
Contents processing portion 2 has obtained after the control signal of selecting judging part 72 outputs, abides by the user with regard to the input operation that the alternative OB shown in this control signal has done, and carries out the picture material corresponding with this input operation and handles (S11).
Like this, even user's contact position departs from from the viewing area P1 of alternative OB, also can detect the input operation that the user is done alternative OA through handling example 1.In addition, can detect the user effectively, thereby prevent the misoperation of 3 d display device 1 input operation that alternative carried out.
< handling example 2 >
Below, another processing routine 2 of the 3 d display device 1 of this embodiment is described with reference to Fig. 6.In handling example 2, will the processing under the following situation be described.This situation is: after user's input operation, then carry out next input operation with same display frame request user.
Fig. 6 is the process flow diagram of the processing example 2 of the 3 d display device 1 in this embodiment.As shown in Figure 6, handle example 2 and have step S21～S30.The processing of step S21～27 is identical with the processing of step S1 shown in Figure 5～S6 and S10, therefore omits explanation at this.
At S27,, then select judging part 72 to be judged as and be selected with the corresponding alternative OB of this surveyed area A if the coordinate figure of user's contact position is included in the coordinate domain of surveyed area A interior (being " being " at S27).Then, select judging part 72 to generate in order to expressing the selecteed control signal of this alternative OB, and this control signal is exported to contents processing portion 2.
Contents processing portion 2 has obtained in order to after expressing the selecteed above-mentioned control signal of alternative OB from selecting judging part 72, judges whether and will ask the user to proceed next input operation (S28) with same display frame.
If need the request user proceed next input operation (being " being ") at S28, the coordinate information of the alternative OB that has been selected to 73 outputs of grand output adjustment part of contents processing portion 2 then.
Grand output adjustment part 73 obtained from 2 outputs of contents processing portion behind the coordinate information of selecteed alternative OB; Change the coordinate information of this alternative OB; Reducing the grand output of this alternative OB, and the coordinate information after will changing is exported to contents processing portion 2 (S29).
Contents processing portion 2 has obtained after the 73 output control signals of grand output adjustment part, and the coordinate information after changing is exported to the three-dimensional depiction engine 3, so that display screen 51 demonstrates the image after the grand output reduction of selected alternative OB.Contents processing portion 2 also exports to control part 7 with the coordinate information after the change of this alternative OB so that control part 7 reset out with reduce after the surveyed area (S24) that matches of grand output.
On the other hand; If need not to ask the user then to carry out next input operation (is " denying " at S28); Then contents processing portion 2 is same with step S11 shown in Figure 5; Abide by the input operation that the alternative OB shown in the control signal that the user just selects judging part 72 outputs is done, carry out and the corresponding picture material of this input operation is handled (S30).
Like this, through handling example 2, therefore the user can improve user's visibility and operability from visually distinguishing alternative OB and the unselected alternative OB that has selected.
